BUILDING-WALL.

Specification of Letters Patent.

Patented Aug. 20, 1907.

Application filed May .6, 1907. Serial No. 372,174.

To all whom it may concern:

Be it known that 1, WILLIAM GURLETT, a citizen of the United States,residing at San Francisco, in the county of San Francisco and State ofCalifornia, have invented new and useful Improvements in Building-Walls, of which the following is a specification.

My invention relates to walls of hollow building blocks, and consists inthe provision in such a wall of an inexpensive, easily applied andefficient device for connecting the meeting ends of two blocks togetherand holding a superposed block against lateral movement out of alinementwith the lower blocks.

The present invention is designed as a specific improvement upon thedevice constituting the subject matter of my contemporary application,filed September 26, 1906, Serial Number 336,361; and its novelty,utility and practical advantages will be fully under stood from thefollowing description and claims when the same are read in connectionwith the accompanying drawings, forming part of this specification, inwhich:

Figure 1 is a broken perspective view showing the clip or connectingdevice comprised in my improvements as properly arranged relative tohollow building blocks in wall. Fig. 2 is a transverse vertical sectionof the same. Fig, 3 is a perspective view of the clip, removed. Fig. 4is a detail vertical section taken at a right angle to Fig. 2.

Similar letters designate corresponding parts in all of the views of thedrawings, referring to which:

A A are hollow building blocks or tiles arranged end to end. B is asimlar hollow block or tile arranged with its intermediate portion abovethe joint between the lower blocks or tiles, as shown by full and dottedlines in Fig. 1, and G is my improved clip. The said clip is preferably,though not necessarily made of sheetmetal, and it comprises a flat body(1, end flanges b reaching upward at right angles from the body, andflanges c struck from the body a and reaching downward at right anglestherefrom. I prefer to have the flanges c depend from the outer walls ofthe openings d, formed by the displacement of the flanges from the body,and I also prefer to arrange two of the flanges adjacent to one edge ofthe body, and two adjacent to the opposite edge thereof. The pairs offlanges care arranged a distance apart slightly greater than thecombined thicknesses of the meeting end walls of the lower blocks, andhence it follows that the clip may be readily made to straddle saidblocks with a view of strongly holding the lower blocks together.

In the practice of my invention, the blocks A are arranged end to end asillustrated, and the clip 0 is arranged so that it straddles the meetingend walls of said blocks and is enabled to strongly hold the sametogether and against endwise movement with respect to each other. Theupper block B is then arranged so that its intermediate portion restsover the flat body a of the clip, and above the joint between the blocksA, and with. its side walls, preferably the outer sides of said sidewalls, in snug engagement with the flanges b of the clip, when, as willbe readily understood, the block B will be securely held in alinementwith the lower block and against lateral displacement in eitherdirection.

The operation described in the foregoing is continued throughout thebuilding of the wall; and it will be observed that the clips C areadapted to be quickly and easily placed in position and are calculatedto facilitate the placing of the intermediate portions of upper blocksover the joints between the blocks on which the upper blocks aresuperposed. It will also be noted that by connecting the meeting endwalls of the lower blocks together and holding the intermediate portionsof upper blocks, the clips 0 contribute materially to the strength anddurability of the wall.

By virtue of the flanges 0 being struck from the body a, it will beobserved that my novel clip may be economically formed of acomparatively small piece of sheet-metal, and it will also be observedthat the body a is enabled to lend stiffness and strength to the saidflanges c.

Having described my invention, what I claim and desire to secure byLetters-Patent, is:

1. A wall comprising lower, hollow bloclis arranged end to end, an upperblock superposed on the lower blocks, and a clip having a flat bodyresting on the meeting end walls of the lower blocks and between theupper edges of said end walls, and the upper block, flanges or armsstruck from the body at points intermediate opposite edges thereof andreaching downward at right angles to the body and a"-ranged at the innersides of the meeting end walls of the lower blocks to hold said blockstogether, a flange or arm reaching upward at a right angle from one endof the fiat body and opposed to one side of the upper block, and aflange or arm reaching upward at a right angle from the opposite end ofthe flat body and opposed to the opposite side of the upper block; saidupwardly reaching flanges or arms being adapted to hold the upper blockagainst lateral displacement.

2. A wall cpmprising lowe1','h0llow blocks arranged end to end, an upperblock superposed on the lower blocks, and a clip having a flat bodyresting on the meeting end walls of the lower blocks and between theupper edges of said end walls and the upper block, flanges or armsstruck from the body at points intermediate opposite edges thereof andreaching downward at right angles to the body and arranged at the innersides of the meeting end walls of the lower blocks to hold said blockstogether, and

'fianges or arms reaching upward at right angles from the flat body andsnugly receiving the upper block between them.

3. As an article of manufacture, a metallic clip for the purposedescribed comprising a flat body, flanges or arms struck from the flatbody at points intermediate opposite edges thereof and extendingdownward therefrom, and flanges or arms extending upward from theopposite ends
